Egypt - Climate and when to go to Egypt

Climate
Throughout Egypt, days are commonly warm or hot, and nights are cool. Egypt has only two seasons: a mild winter from November to April and a hot summer from May to October. The only differences between the seasons are variations in daytime temperatures and changes in prevailing winds. In the coastal regions, temperatures range between an average minimum of 14° C in winter and an average maximum of 30° C in summer.
Temperatures vary widely in the inland desert areas, especially in summer, when they may range from 7° C at night to 43° C during the day. During winter, temperatures in the desert fluctuate less dramatically, but they can be as low as 0° C at night and as high as 18° C during the day.
The average annual temperature increases moving southward from the Delta to the Sudanese border, where temperatures are similar to those of the open deserts to the east and west. In the north, the cooler temperatures of Alexandria during the summer have made the city a popular resort. Throughout the Delta and the northern Nile Valley, there are occasional winter cold spells accompanied by light frost and even snow. At Aswan, in the south, June temperatures can be as low as 10° C at night and as high as 41° C during the day when the sky is clear.
 
When to go
The best time to visit Egypt is from October to April when the weather is a little cooler.
